# 123猜猜猜™ (香港版) vs BRAIN 99

The clearest difference is rating: BRAIN 99 at 5.0 against 123猜猜猜™ (香港版)'s 2.5. BRAIN 99 also leads on update cadence (every 8 days vs monthly) and iOS requirement (12.0 vs 15.0). 123猜猜猜™ (香港版)'s advantage is review sentiment (70% vs 60%) and ratings volume (8 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 123猜猜猜™ (香港版) sells 10 one-off in-app purchases and BRAIN 99 sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

BRAIN 99 holds the better App Store score, 5.0 against 2.5. Both are backed by a comparable volume of ratings — 8 and 2 respectively. Written reviews complicate that: 70% of 123猜猜猜™ (香港版)'s written reviews are positive against 60% of BRAIN 99's, so the app with the better star average is not the one people write more warmly about.
